  • The primary ii-V-I progression (Fm7-Bb7sus-Ebmaj7) grounds the harmony in Eb major, frequently enriched by the bVII7 chord (Db7).
  • The bVII7 (Db7) is often employed in unexpected ways, such as leading to C7 (V7/ii) rather than directly to Ebmaj7, adding a distinct modal flavor.
  • Tritone substitution is evident with A7#11 resolving to Abmaj7, functioning as a reharmonization of V7/IV (Eb7).
  • Chromatic dominant movements like E7-F7 introduce passing harmonic tension, creating sophisticated temporary tonal shifts.

Improvisation Focus: Navigating altered dominant scales and their corresponding resolutions.

Difficulty Rating: 4 (Advanced Intermediate). The frequent use of non-diatonic dominants, tritone substitutions, and unexpected resolutions requires a sophisticated harmonic ear and scale knowledge.
